the lower portion of the wheel being en 2Qfat its upper end whereby'itcan turned 3 59 surface over which the device is passing. A From the foregoing it will be seen that when the toothed'bar is in horizontal position, it will slide on the ground so that it will act as a runner and support one side of the housing while the wheel is supporting the other side. The rotary movement of the wheel is transmitted to the cutter bar to reciprocate the same through means of the pitman and the shaft 9 so that the cutter bar will be reciprocated as the machine is pushed or pulled along. cut grass of any length and when the toothed bar is swung upwardly the 'device can be moved along and passed through narrow gates and the like without'difliculty.

As will be seen, the device has but coinparatively few parts and it can be kept in repair with but the use of a few tools.

It is thought from the foregoing description that the advantages and novel features of my invention will be, readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of'the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is i 1. A lawn mower comprising a housing, a ground wheel at one side thereof, a toothed bar including a vertical portion hingedly connected with one side of the housing, whereby said bar can be arranged horizontally for use or vertically when not in use, a cutter bar slidably mounted on I said toothed'bar, means for reciprocating said cutter bar from the ground wheel, including a pitman, said toothed bar having a slot, a resilient latch element projecting from the housing and arranged to be received by said slot when the bar is swung .to a vertical position anda member rotatablyisupported on the housing and adapted to beiarranged beneath the pitman to assist thelateh in supporting the bar in vertical position. 7
